How To Configure Frame Relay in Cisco Packet Tracer

Configuring frame relay encapsulation is a little bit tricky and complicated. However, it is not as difficult as people think. In this post, we will explain a step by step guide to configure frame relay in Cisco Packet Tracer. However, we will not cover the theory part of the frame relay technology in this post. We assume ou are already familiar with basics of Frame Relay technology. You may use either Cisco Packet Tracer or GNS3 simulator depending on your choice.

Creating Frame Relay Topology in Cisco Packet Tracer

First of all, add all the routers and a frame relay switch in Cisco Packet Tracer. Next, interconnect all the devices using the appropriate interfaces as mentioned in the preceding topology. Once you have created the topology, the next step is to specify the frame relay interfaces, DLCI, and other parameters. To do so, you need to perform the following steps:

In the right pane, select the values in the following order from the drop-down lists, and then click Add. It will create a frame-relay connection between Router1 and Router3.

Next, select Frame Relay under CONNECTIONS.

Next, select Serial2 interface, type 301 in the DLCI field, type R3-R1 in the Name field, and then click Add.

Next, select Serial1 interface, type 201 in the DLCI field, type R2-R1 in the Name field, and then click Add.

Again, type 103 in the DLCI field, type R1-R3 in the Name field, and then click Add. After performing these steps, the Cloud0 properties dialog box should look like the following figure.

Type 102 in the DLCI field, type R1-R2 in the Name field, and then click Add.

Double-click on Cloud0. On the Cloud0 properties dialog box, select Serial0 under INTERFACE.

Seria0

R1-R2

Serial

R2-R1

Again, select the values in the following order from the drop-down lists, and then click Add. It will create a frame-relay connection between Router1 and Router3.

Serial0

R1-R3

Serial2

R3-R1

The following figure to shows how to make the frame-relay connections.

Once you have created the frame-relay connections, close the Cloud0 properties dialog box.

Steps to Configure Frame Relay in Cisco Packet Tracer

After creating the frame relay topology, the next step is to configure frame relay. You can configure either point-to-point or point-multipoint frame relay depending on your requirement. In this demonstration, we will configure point-to-point frame relay. To do so, you need to execute the following commands:

Move on to Router1 and execute the following commands to enable frame relay encapsulation on the se2/0 interface.

Verifying Frame Relay Configuration

Now, you have configured the point-to-point frame relay encapsulation on all the routers. Next, verify your frame relay configuration. To do so, execute the following commands on Router3 and examine the output of each command.

Router3#show frame-relay pvc
Router3#show frame-relay map

The following figure shows the frame relay verification commands.

In the preceding figure, you can see that frame relay encapsulation has been configured on the Serial2/0 interface of Router3. Use the same commands to verify your frame relay configuration on Router2 and Router3.
